Objectives : The mechanical properties of Korean electric cupping systems are studied via experimental measurements. The study aimed at establishing the fundamentals of industrialization and systemization of oriental medicine device industry, as well as improving the quality of life for many Koreans. Methods : We reviewed the studies on traditional cupping as well as modern one to fine necessary factors for electric cupping systems. To characterize the mechanical properties of Korean electric cupping systems, we measured the pressure characteristics of commercially available electric cupping system by using an automatic pressure acquisition system and a standard cup. The pumping capability was checked at 40 seconds, and the stability of the suction cup was checked at 600 seconds. We also acquired the noise level of each system in clinical setting. To check the portability of each system, we also measured its physical dimensions. We scrutinized system manuals provided by the system manufacturers. Results : It took less than 5 second to reach the pressure if the connection between the air hose and the vacuum valve of the cupping system was secure. Pressure diminished to no more than 10% for 600s for all systems. Noise levels were 55~70 dB. Increase in pressure was too fast to control for a designated vacuum level except for one product. Conclusions : The Pumping ability of the systems is impressive and reliable. Pressure retention ability of each cup is quite reliable and reproducible. Therefore, their mechanical performances were worthy of recommendation. Some of them had noise level higher than 60 dB and they were bothersome. It was also suggested that the control for low to middle pressure needed to be accomplished by the cupping system.

초 미약 생물광자의 이차원적 영상을 얻기 위해 고속 초고감도 CCD 사진기를 검출기로 사용한 실험 장치를 고안하였다. 본 장치에는 식물의 잎으로부터 방출하는 지연광 (delayed luminescence)를 발생시키기 위한 조명 장치를 설치하였으며, 조명 장치와 검출기에 있는 셔터들은 서로 연동되어 동작하도록 이루어졌다. CCD 사진기에 사용된 렌즈계는, 상용렌즈들로만 구성되었는데, 시료에서 나오는 생물광자의 집광 효율 (collection efficiency)을 높이도록 최적화된 렌즈 설계에서 나온 결과를 기초로 하였다. 이 장치들을 다용도 암 상자에 장착하여 사철나무 잎에서 나오는 지연광의 영상을 성공적으로 얻었다. We developed a 2-D imaging system to detect ultra weak biophoton by using a high sensitive fast CCD camera. We installed an illumination apparatus to generate delayed luminescence from plant leaves. Shutters at the illumination system and detector were synchronized to each other. The lens system of the CCD camera was newly designed to accommodate the specific requirements to enhance the collection efficiency for biophoton. Based on the lens simulation, commercial lenses were chose for the lens system. All the equipment was installed in a multi-purpose dark box and the delayed luminescence of Euonymus japonica was successfully acquired.

Objective: The purpose of this study is to review research papers on low level laser therapy (LLLT) and to improve the knowledge of LLLT field. Methods: For introduction, laser characteristics, including wavelength, medium, beam size, power, and unit power were explained. In order to understand LLLT, tissue optics and light-biomatter interaction were briefly mentioned. We reviewed 21 Korean papers on laser acupuncture and LLLT on the viewpoint of laser apparatus. Results and Conclusion: We found that the description of laser apparatus employed for LLLT experiments were not fully written. Laser wavelength and power which are the most crucial parameters, were omitted in several papers. No paper had information on beam size. In order to have high efficacy, laser should be used with proper laser parameters. Conditions of irradiation area or acupoints should be considered too. Some future technology on laser acupuncture were mentioned.

Objectives: The purpose of this study is to introduce and examine the possibilities of infrared (IR) imaging, biophoton detection and gas discharge visualization(GDV) as diagnostic tools in Korean Medicine. Methods: To review the basic mechanism and measurement methods of three modalities, concepts in physics were introduced. Physical backgrounds of IR, biophoton and GDV were briefly explained based on recent research papers. Simple electronics was employed for relevant detectors. In order to find the relation between Korean Medicine and these methods, papers on their applications were reviewed. Opinions from the experts on each modality were obtained from their papers and private communications. Results and Conclusions: IR imaging has been used as an auxiliary diagnostic tool but there are some rooms for the improvement for clinical applications. Experimental confirmation of the meridian activation by a moxa cigar is necessary for its verification. Biophoton is not correlated with human skin temperature but it has a circadian rhythm. Biophoton and GDV have a negligible relation if any. Therefore there are no correlations among three modalities in terms of basic mechanisms. But their clinical relations are yet to be scrutinized. Biophoton and GDV need more rigorous clinical tests before they can be used as diagnostic tools.

이동 에이전트 시스템의 응용 분야가 점점 넓어지고, 사용자가 좀 더 강력한 에이전트를 요구함에 따라 이동 에이전트의 협력 작업이 필요하게 되었다. 그러나 기존의 에이전트 협력 방법인 주(master)-종(slave) 구조는 빈번한 원격 통신으로 인한 네트워크 오버헤드, 주 에이전트에의 과도한 부하 등의 단점을 가지고 있다. 본 논문에서는 이러한 단점을 보완하기 위해 기능 분할(function division)을 통한 에이전트 그룹 협력 모델을 제시한다. 이 모델은 주 에이전트와 종 에이전트의 기능을 나누어 에이전트 프로그램 개발, 관리의 용이, 네트워크 트래픽 감소, 네트워크 병목현상 해결, 네트워크 오버헤드 감소 등의 효과를 가져온다.

Aluminum doped zinc oxide (AZO) films were deposited on non-alkali glass substrate by DC magnetron sputtering with 3 types of AZO targets (doped with 1.0 wt%, 2.0 wt%, 3.0 wt% Al₂O₃). Electrical, optical properties and microstructure of AZO films have been investigated by Hall effect measurements, UV/VIS/ NIR spectrophotometer, and XRD, respectively. Crystallinity of AZO films increased with increasing substrate temperature (Ts) and doping ratio of Al. Resistivity and optical transmittance in visible light were 8.8×10 ?⁴ Ω㎝ and above 85%, respectively, for the AZO film deposited using AZO target (doped with 3.0 wt% Al₂O₃) at Ts of 300℃. On the other hand, transmittance of AZO films in near-infrared region decreased with increasing Ts and doping ratio of Al, which could be attributed to the increase of carrier density.

박막 및 디스플레이 분야에서는 광학 부품소재의 우수한 광 투과성과 투명성을 요구하는 수요가 증가함에 따라 우수한 반사방지 특성의 부여에 대하여 관심이 집중되고 있는 실정이다. 본 연구에서는 반사방지 기능을 부여하기 위하여 졸-겔법에 의한 수열합성법을 통하여 기저 물질 표면에 산화알루미늄을 나노 크기 꽃 형태의 프레임 구조를 가진 단일 산화물층을 형성시키고자 하였다. 코팅 층 시편의 특성은 UV-Vis 분광기, FT-IR 분광기, XRD 및 FE-SEM을 이용하여 분석하였다. 알루미나 졸이 코팅된 시편들의 모폴로지는 수열합성의 온도와 시간 및 초음파 제공에 의해 조절되도록 하였다. 꽃 형태의 나노 프레임 구조 형태로 구성된 코팅 층에서 높은 광투과율과 반사방지특성이 발현되었다. Highly anti-reflective optical property has been focussed in the field of thin film and display because of increasing demands to the high transparency and clearness of optical component. In this study, to obtain anti-reflective property, the formation of aluminium oxide with nanoscaled flowerlike frame structure was introduced as oxide material monolayer on the substrate by hydrothermal synthesis through sol-gel method. The properties of coating layer were measured by the means of UV-Vis spectroscopy, FT-IR spectroscopy, XRD, and FE-SEM. The morphology of coating layer in alumina-sol coated samples was controlled by hydrothermal temperature and time with aid of ultrasound. It was found that high transparency and anti-reflective optical properties were obtained the formation of flowerlike nanoframe structure.

Objectives: Accurate and reproducible location of an acupuncture point (AP) have been considered an essential component of meaningful acupuncture research as well as clinical practice. Several kinds of devices have been developed and widely used for the convenience of locating APs. However, the accuracy and convenience of these devices have not been systematically evaluated. The present study was performed to find out the most suitable tools for the location accuracy and location easiness of APs among the devices respectively. Methods: Twenty subjects attempted to locate APs, including PC5 and SP6 in the arm and leg, using four different AP positioning methods: one Conventional Ruler method and three alternative methods including Cunometer, Transparent AP meter, and Elastic Ruler method. The position marked on each AP was plotted onto a thin, flexible, and transparent plastic film, and the dispersion rate of the positions was determined and recorded. The elapsed time for locating each AP was measured. After that each subject was answered to a short questionnaire regarding the degree of convenience and confidence of use of each method for AP location. Results: All of three alternative methods took less time than Conventional Ruler method did. Among these alternative methods, the accuracy of Elastic Ruler method was markedly higher than others. The degree of convenience of the Cunometer and the confidence of Elastic Ruler method were the highest among these alternative methods. Conclusions: The present study indicates that the Elastic Ruler method was the most compatible for the conventional Ruler methods. However, there are many factors need to be reconsidered. Improved devices for locating AP are imperatively needed for clinical practice.
